In November 1781 Mozart, in a letter to his father, mentioned the composition of this Serenade: ‚I wrote this music for St Theresa’s Day [15 October] – for Frau von Hickl’s sister, or rather the sister-in-law of Herr von Hickl, court painter. But the chief reason why I composed it was in order to let Herr von Strack, who goes there every day, hear something of my composition; so I wrote it rather carefully.‘ Instrumentation: 2 horns, 2 oboes, 2 clarinets and 2 bassoons KV 375
